l 7 Claims. This invention relates to windows such as the Windows ofautomobiles which are capable of being raised and lowered and which aresupported within the automobile body below the 5 belt or within the doorbody; and it has for its object a particularly simple, eicient andcompact means for supporting the window sash and holding it fromlooseness and rattling when in both its open and closed position, andfor so supporting' the sash that it can be raised and lowered withlifting mechanism without binding due to edgewise thrust of the sash,particularly if the lifting force is applied unevenly or more toward oneside of the sash than the other. Another object is a particularly simpleand eflicient sash guide means.

lThe invention consists in thenovel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had' to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is a fragmentary elevation, partly broken away, of anautomobile door to which our invention is applied.

I designates the supporting body here illustrated as the hollow body ofan automobile door. 2 designates the sash, which preferably has amarginal frame consisting of top and bottom rails 3 and 4 and stiles 5.The sash is guided by means located Wholly Within the door body I, andthis means includes a guidelocated in the door body between the verticallines of the stiles 5 and preferably about midway between such lines;The sash is provided with a carriage depending from the intermediatepart of its bottom rail Iand movable along the guide, the carriagelbeing offset from the-plane of the sash or out of the path of the sash,as seen in Figures 2 and 4. The carriage and the guide are provided withcoacting means for holding the sash from edgewise movement and also frommovement in a direction at an angle to the plane of the sash. 6designates the guide which is here shown as in the form of opposingchannels, these channels being formed up from the opposite marginalportions of a base 1. The guide is secured in the door in any suitablemanner, it being generally secured to cross frame members 8 by screws 9passing through the base 1.

I0 designates the carriage which depends from the bottom rail 4 of thesash. It is connected to the bottom rail by a curved bracket II so thatthe carriage is offset from the plane of the sash. The side margins ofthe carriage extend into the channels and are provided withanti-friction means as a pair of spaced apart rollers I2 at each sideedge. Each roller is mounted on a stud I3 and has anti-friction bearingsI4 on the stud. The ends of the studs slidably engage' like side Wallsof the channel and the margins of the carriage slidably engage the otherside walls of the channels so that by reason of this engagement the sashis held from vibrating in a direction at an angle to its plane. One pairof rollers run on the bottom of one channel and the other pair along aspring pressed track I5 extending substantially parallel to the bottomof the other channel. The spring pressed track provides means forholding the sash from edgewise movement or vibration.

Usually in sashes used in automobile construction, the sashes are guidedwholly at their side margins or by vertical extensions as 20 of thestiles running in channels or along guides as 2| within the door orautomobile body. As

channel and then bulging the straps outward, V

leaving their ends joined to the side wall. The extensions 20 serve tormly support the sash when closed. However, edgewise movement or play isprevented by the guide 6 and carriage Ill.

As seen in Figures .7 and 8, the guides 2| may be unprovided with thespring pressed tracks and the extensions 20 of the stiles provided withspring pressed shoes thrusting against the inner faces of the side wallsof the channels 2|. The shoes are preferably arranged in pairs spacedapart along the extension 20. 30 designates the shoes pressed by springs3| located in the channel of the extensions and arranged to press theshoes outward, the shoes being interlockedwith the extensions to holdthem from displacement. As shown, the shoes consist of a base plate 32on the inner side of the channel and having a projection 33 extendingthrough a hole 34 in the side flange of the channel of the extension soas to engage the side flanges of the channel shaped guide 2|. The shoesare fibre faced and preferably the entire shoe is a flbre block. 'I'hesprings 3| are coiled springs and each seats at one end around aprojection 35. 'I'he projection 35 is here shownA as a pin having acollar 36 thrusting against the inner face of the side flange of theguide 2| and having a guide pin 31 extending in a perforation in saidside flange. The projections 35 holds the springs from displacement.This construction of guide means for the sash is especially simple,practical and economical. l

The lifting mechanism usually consists of an arm or a pair of arms 38operated by a suitable crank 39, the arms having rollers which work in atransverse groove 40 formed -along the bottom rail. 'I'he resultant ofthe lifting forces of the two arms is not always parallel to the guideand hence, the sash is subject to an edgewise thrust Which causes it tobind more or less, and when but one lift arm is used, the binding effectis more pronounced. By our invention not only is the binding effecteliminated but-the sash is held against 'misalinement either when thelifting force is applied directly to the bottom rail of the sash or tothe carriage.

'What we claim is:
